Guest guest Posted June 15, 2005 Report Share Posted June 15, 2005 : We don't know nor do most of us care about your qualifications. After all anyone can call themselves anything they wish in the anonymous world of cyberspace. (And I'm reminded of the old joke that 50% of all doctors graduated in the bottom half of their graduating class!). But you did post your wc/h measurements recently which are a pretty good indicator of thinness. And you seem to be avoiding telling us how much you actually weigh and how tall you are (which of course is your perfect right!). In the aforementioned post you said: " My ratio is .37 but I will get it even lower. Possibly .33. Not that I really try but I estimate I have another 20 lbs or so of adipose to lose at a minimum. Anyone else have a ratio under .35? " You will forgive us for thinking this is typical anorexic behavior i.e. saying you intended to get even thinner than what seems to be extremely thin, and intimating that this is some sort of thin " contest " . Of course I could be misinterpreting those remarks and of course you have a perfect right to do whatever you want, but posting those numbers leaves us with an obligation to tell people that we do not advocate extremism. BTW we have one admitted anorexic in the group here (whom we greatly admire for his forthrightness and his battle) and your wc/h measurements are MUCH lower than his. And we do have studies backing up Tony's assertions which are in the " Extreme vs Moderate " file . In that file, you will also find testimony of people who tried extreme CR (and suffered mentally from it). on 6/15/2005 2:56 PM, drsusanforshey at drsusanforshey@... wrote: > You are questioning my qualifications?

Guest guest Posted June 16, 2005 Report Share Posted June 16, 2005 Choose your own path and good luck. I believe there is a logical flaw in offering body builders as examples of extremely low BF levels. I'm sure they have more than adequate fat they just have so much muscle that as a percentage it looks small.

Guest guest Posted June 16, 2005 Report Share Posted June 16, 2005 Agreed but I think you may be missing my point. 9% BF for a body builder who weighs significantly more, is " more " pounds of fat than 9% for a low BMI CR'd individual. This also doesn't account for the difficulty in accurately measuring structural and organ fat. I wouldn't expect a heavier bodybuilder to have bigger eyeballs or a bigger brain. :-) So IMO, body builders %BF are not strictly comparable, and even if they were they don't seem to be particular examples of good health.

This process is called " cutting. " They spend most of the year " bulking, " i.e., eating hypercalorically in order to add lean muscle mass, but in the process they also tend to add fat and their bodyfat may hover at levels as high as 20% or more for many months at a time. It's important to bear in mind that competitive sports aren't about health, they're about winning, often at any cost. Many if not most competitive bodybuilders also use potentially dangerous anabolic and/or weight loss drugs. Longevity isn't their primary goal. -Liz Quote Link to comment Share on other sites More sharing options...
Guest guest Posted June 16, 2005 Report Share Posted June 16, 2005 I believe we are in far more agreement than disagreement. %BF measurements seem almost too inaccurate to bother with. Caliper measurements are based on lots of assumptions too so I suspect a 51YO weight trainer may not fit typical profiles very well. I can even imagine small errors in the immersion method due to different lung capacity. For example a runner may have more hot air. I'm not familiar with Futrex but it sounds like a bio-impedance based device and from mine and others experience with Tanita, this approach is hugely influenced by hydration (as you mention) and again based on gross assumptions. Many low BMI CR'd individuals attain negative %BF readings on Tanita's (oops). I may rely a little too much on the mirror test (healthy should look healthy), as this is also subject to cultural distortions. I'm sure I don't look healthy to my overweight neighbors here in MS, and some individuals suffer from distorted perceptions of self. IMO all of this argues against micro-management and extreme targets.

I just wanted to add the point that bodybuildres don't KEEP their bodyfat at minimal levels for very long. (Also, as an aside, there is in fact medical evidence that bodybuilders who take anabolic steroids do have significantly larger internal organs, often to their detriment.) Another important factor to keep in mind is that most measurements of bodyfat are pretty innaccurate. I test mine monthly using a Futrex 5000 machine at my gym, as well as calipers, tape measure, and the experienced eyeballs of several professional trainers. The Futrex is particularly inaccurate at lower bf levels, and it fluctuates infuriatingly depending on hydration, body temp, recent activity, the moon, the stars, the harmonic convergence, who knows. Testing total bf with calipers depends on using an equation that factors in age and sex, which is always way off for me because it assumes a woman my age has much less muscle mass and bone density than I in fact do. For example, if I enter my age as 51, which it is, my result is 23% bf, but if I tell it I'm 21, it says my bf is around 14%, which is close to what the Futrex & other measures usually indicate. And because I'm a weight lifter, I do have way more muscle than the average 51 year old woman, and my bone density is very high--t scores range between +1 and +2, which is the score of a healthy 18 year old. Anyway, the point of all this is that these measurenments tend to NOT be accurate, so there's a high likelihood that any given person may be assuming an incorrect value for their bf%, either too high or too low. So maybe when they think they're going down to 10% or whatever, it wouldn't cause any problems at all because their initial calculation was a false low, and they're not actually anywhere mnear 10%. But a person could also run into serious trouble if the calculation was false high. Just something to keep in mind when talking about bodyfat percentages: unless you've been dunked or had an autopsy, your estimate is probably off. -Liz Quote Link to comment Share on other sites More sharing options...
